As police continue to investigate the motive behind Tuesday's triple murder near the UNC campus, more details have emerged about the three victims in the case, which include a just-married couple -- Deah Shaddy Barakat and Yusor Mohammad -- and wife Yusor's younger sister, Razan Mohammad Abu-Salha.

His 21-year-old wife, Yusor, had plans to begin studies at the UNC Dentistry school in the fall. The couple were married on December 27 and worked with the YouCaring fundraising site on the Syrian Dental Relief project to provide dental care for Syrian refugees in Turkey.

The project raised three times its $20,000 goal and Deah -- whose family is from Syria -- wrote about his experience in the pitch for funds:

"In summer of 2015, I as well as 10 local dentists and faculty from UNC School of Dentistry will embark on a trip to Rihaniya, Turkey to provide dental care to students of Salaam School. Hundreds of students are currently in need of urgent dental care, mainly consisting of fillings and extractions. Following each procedure, we will provide oral hygiene instructions and fluoride treatment to prevent future tooth decay."

A spokesperson for UNC Chapel Hill told the Associated Press that the couple both graduated from North Carolina State University, with Deah receiving a business administration degree in 2013 and Yusor finishing her biological sciences degree in December.

Muneeb Mustafa, 23, attended the same Raleigh mosque as Deah and described the dental student as a kind, generous person. "He was a completely genuine guy. Loving, caring, friendly, smart," Mustafa said. "He was an ideal human being. He was a role model."

Two weeks ago, Deah posted a photo and gushed about participating in the DowntownSmiles project, which provided "free dental supplies and food to more than 75 homeless people in downtown Durham!"
